Update: Even while declaring an international public health emergency, the WHO are not advising against travel, so the size of any impact is likely to be pretty modest:
The Committee found no public health justification for restrictions on travel or trade to prevent the spread of Zika virus.
At present, the most important protective measures are the control of mosquito populations and the prevention of mosquito bites in at-risk individuals, especially pregnant women.
tldr It's very unpredictable and could go either way - probably a little bit of both.
Based on my experience of such things, it'll fluctuate as the supply and demand fluctuate. It's likely to go down, then up, then down but not as much as it went up - but the amounts, or amounts of time taken in each phase, could be barely noticeable, could be dramatic, and will almost certainly vary between airlines. Here's a typical pattern:
However, these examples are extreme cases. It's quite likely zika will have a much smaller impact than Ebola or the Arab Spring.

Not the expert in this field, but in my opinion, prices will not go down. Oil prices went down big time, and ticket prices didn't change a bit. Other epidemics in the past few years did not end up making ticket prices lower.
What happens is, people are scared to go to Latin America, fine! airlines will simply make flights less to that part, and see where do people want to spend their vacations now, and add more flights to the new destinations! no one needs to make ticket prices lower.
An example, when the Arab spring started (a name for the revolution that took place an various Arab countries), Middle Eastern airlines changed their routes a bit, more flights to Europe and the far East, less flights to Egypt, Tunis, Syria. Ticket prices were never reduced, not even a cent, but since people changed their regular holidays destinations, airlines did as well.
Bottom line, IMO, airlines just started making some money because of the oil prices do you think a zika virus will make them lose that? I didn't think so. It's just changing the routes to where people demand.
